Historical Foundations and Early Milestones
The firm was established in 1885 in New York City by civil engineer William Barclay Parsons. One of its most enduring early achievements was the design of the original IRT line of the New York City Subway, which opened in 1904 and fundamentally changed urban mobility.
In 1906, the firm expanded its technical capabilities when highway engineer Henry M. Brinckerhoff joined. Brinckerhoff brought specialized knowledge in electric railways and is credited as a co-inventor of the third rail—the electrified third rail used to power trains.
Beyond New York, the firm's early portfolio included the Cape Cod Canal (opened 1914) and a railway line in China connecting Hankow (Wuhan) to Canton (Guangzhou), which remains in use today.
A Century of Infrastructure Innovation
Throughout the 20th century, the firm became a go-to partner for complex infrastructure projects. Its portfolio includes a diverse array of tunnels, bridges, and transit systems across the globe.
Notable 20th Century Projects
- Tunnels and Bridges: The Detroit–Windsor Tunnel (1930), the Scheldt Tunnel in Antwerp, Belgium (1933), the Buzzards Bay Railroad Bridge (1935), and the Pell Bridge in Rhode Island (1969).
- Roadways and Energy: The Garden State Parkway in New Jersey (1957), the Hampton Roads Bridge-Tunnel in Virginia (1957), and the U.S. Strategic Petroleum Reserve (1980).
- Rapid Transit Systems: The firm designed transit networks for San Francisco (1972), Atlanta (1979), Singapore (1987), Taipei (1996), and Caracas (1983).
Evolution into WSP Global
The transition from an independent firm to a global powerhouse occurred through a series of strategic acquisitions. In October 2009, Parsons Brinckerhoff was acquired by Balfour Beatty plc. However, a major shift occurred on October 31, 2014, when WSP Global purchased the firm from Balfour Beatty for US$1.24 billion.
Following the acquisition, the company operated as WSP|Parsons Brinckerhoff before the Parsons Brinckerhoff brand was officially retired in 2017, fully integrating the firm into the WSP brand. To further expand its capabilities, WSP Global acquired the Louis Berger Group in 2018, Ecology & Environment (E&E) in 2019, LT Environmental in 2020, Golder Associates in 2021, and Wood PLC’s Environment & Infrastructure Solutions business in 2022.
Current Projects and Industry Standing
WSP USA continues to lead high-profile infrastructure developments. Recent and ongoing engagements include the Long Island Rail Road's East Side Access to Grand Central Terminal, the redevelopment of LaGuardia Airport in New York City, and the Charlotte Douglas International Airport Airfield Expansion.
The firm's prestige is reflected in industry rankings. In 2020, Engineering News Record ranked the firm #7 among the Top 500 Design Firms and #2 among the Top 100 Pure Designers.

Project Controversies
Despite its success, the firm has faced significant challenges. Most notably, the Big Dig (Central Artery/Tunnel project) in Boston, partnered with Bechtel, was plagued by engineering failures and cost overruns, with budgets ballooning from $8 billion to over $24 billion. The project suffered from substandard materials and a fatal tunnel ceiling collapse.
Other controversies include the Silver Spring transportation center in Maryland, which faced reports of falling concrete and design flaws, and a legal settlement in 2014 regarding the Lane Cove Tunnel in Sydney, Australia, involving claims of misleading conduct.
